Detector

Dose rate estimations for PbWO4 detector at 4m from target, at 1uA, and for a 10-cm long target

Scattering Chamber Information:

  • outer diameter = 45 inches
  • inner diameter = 43.125 inches
  • distance beam line to SHMS window = 1.25 inches

So for a point target, the minimum angle is 58 mr or 3.4 degrees. For an extended target you will need to adjust, it becomes about 4 degree for a 15 cm target. So assume 3.5 degrees as rough number.


Study of possibilities for larger beam pipe assemblies

Energy spectra for electrons, photons, positrons including fits


Rates and rates per crystal vs. angle relative to beam for: 4 m from target, 6.6 GeV beam energy, 1uA beam current, and 10-cm LH2 target for:

Photon threshold=10 MeV

Photon threshold=3 MeV
